DOUBLE MEMORANDUM BOOK Application filed January 8, 1932. Serial N0.'585,405.' I

' This invention relates to new and useful improvements in a doublememorandum The invention has for an object the construction of anarticle of the class mentioned which is characterized by the provisionof a central leaf joining opposite sides of a pair of covers, and leavesin the bends formed by said central leaf and covers.

As a further object of this invention, it is proposed to provide meansfor holding either one of the covers together with the central leaf sothat the other cover may be opened for exposing the leaves of the book.

As another object of this invention it is particularly proposed tosupport a strip through an opening in the central leaf, to mount snapfastener studs upon the ends of the strip so as to engage through thecentral leaf, and to mount socket snap fastener elements upon the coversfor co-action with the'studs to accomplish holding the covers closed.

A still further object of this invention is the construction of anarticle of the class mentioned which is of simple durable construction,dependable in use and efficient in operation and which can bemanufactured and sold at a reasonable cost.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawing, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

In the accompanying drawing forming a 7 material part of this disclosureFig. l is a perspective view of a memorandum book constructed accordingto this invention and shown partly opened. Fig. 2 is a plan view ofFig. 1. Fig. 3 is a fragmentary enlarged sectional view taken on theline 33 of Fig. 1.

Fig. 4 is a view similar to Fig. 2 but illustrating a modification oftheinvention.

Fig. 5 is a sectional view looking in the direction of the line 55 ofFig. 4.

The memorandum book, according to this invention, comprises a pair ofcovers 10 and may be usedfor a different purpose such as the recordingofbirthdays and other data.

In Fig. 3, it should be noted, the covers 10 and 11 are much thickerthan the central leaf 12. The purpose of this is to simulate a singlebook when the memorandum book isin a closed position; that is, theappearance is had that there is but the covers of the book and nothingbut leaves inside.

I In the modified form of the device illustrated in Figs. 4 and 5, ameans has been dis.. closed forjholding either one of the covers closedupon the central leaf. This means comprises a strip 15 passed through aslot 16 in the central leaf 12 and at its ends supporting snap fastenerstuds 17. These studs are directed so as to engage through apertures inthe central leaf 12 and extended from the other side. Snap fastenersockets 18 are mounted upon the covers 10 and 11 and are engageable withthe studs 17 for accomplishing closing of the book. The arrangementallows opening of one of the covers or the other of the covers or bothof the covers simultaneously. When it is desired, the strip 15 may beremoved by bending the first so that the studs 17 disengage from thecentral lle6af 12 and next slipping it through the slot While I haveshown and described the preferred embodiment of my invention, it is tobe understood that I do not limit myself to the precise constructionherein disclosed and I the right is reserved to all changes andmodifications coming within the scope of the invention as defined in theappended claims.

Having thus described my invention, What I claim as new, and desire tosecure by United States Letters Patent is 1. A double memorandum book,comprising a pair of parallel and spaced covers, a central leaf betweenthe covers diagonally joining opposite sides of said covers so as toform a zigzag arrangement, and leaves in the bends between the coversand the central leaf.

2. A double memorandum book, compris- 5 ing a pair of parallel andspaced covers, a central leaf between the covers diagonally joiningopposite sides of said covers so as to form a zigzag arrangement, andleaves in the bends between the covers and the central leaf,

said covers being of rigid material,

3. A double memorandum book, comprising a pair of parallel and spacedcovers, a central leaf between the covers diagonally joining oppositesides of said covers so as t form a zigzag arrangement, and leaves inthe bends between the covers and the central leaf, said covers being ofrigid material, and said central leaf being of thin flexible materia 4:.A double memorandum book, comprising a pair of parallel and spacedcovers, a central leaf between the covers diagonally joining oppositesides of said covers so as to form a zigzag arrangement, leaves in thebends between the covers and the central leaf, a strip passed through aslot in said central leaf so that its ends extend on opposite sides ofthe central leaf, snap fastener studs on the ends of said strip engagingthrough apertures in the central leaf,'and complementary snap fastenersockets upon said covers for engaging said studs.

In testimony whereof I have affixed my signature.
